The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got Kennebunk Beach on the table, and I gotta be honest with you, the next couple of weeks are looking pretty grim for a proper paddle. The setup is sheltered, so it takes a lot to get it going, and we just don’t have the right juice or the windows of clean wind to make it sing.
The first real chance to even think about a session doesn’t pop up until Wednesday, September 2nd. Even then, it’s not pretty. The morning shows a small 4 ft SE swell, with a period of just 6 seconds. That’s weak, short-period windswell with combined energy of 160 (moderate), and the wind is cross-offshore from the east. It’s clean, but the waves will be small and weak. That afternoon, the swell drops to 2 ft, but the period jumps to 11 seconds. That’s a longer period, which brings a bit more shape, but the size is tiny. The cross-off wind stays light, so it’s clean, but don’t expect much push.
Thursday the 3rd sees a bump in size, with 6 ft on the morning and 5 ft in the afternoon, both from the SSE/SE. The combined energy jumps to 241 and 251 (strong), but here’s the kicker: the wind is a mess. Morning is a cross-shore chop with moderate breeze, and the afternoon, while clean, is a fresh 19 mph cross-off. That’s more of a kite-surfing breeze than a paddle-friendly one. The short 6-7 second period means the waves will be crumbly and messy.
We get a little window of hope on Friday the 4th and Saturday the 5th. Friday morning has a tiny 3 ft from the east with clean offshore winds from the NE. Glassy conditions on Saturday morning with a 3 ft ESE swell. These are the cleanest, most inviting windows in the whole run, but the swell is tiny. For a beginner, the 3 ft is fine, but the lack of power means it’ll be a longboard or foamie kind of day.
The second week is a write-off. There’s a brief pulse on Monday the 7th with 3 ft swelling from the east and a 9-second period, with clean cross-off winds in the morning. Combined energy is 168 (moderate), but it’s the only decent look in that whole week. After that, it’s nothing but onshore wind, tiny swell, or massive wind-affected junky conditions. By Wednesday the 9th, we see 8 ft of junky cross-onshore slop, and by Thursday the 10th, it’s the same story. That’s not surf, that’s a washing machine.
The water temperature is sitting at 67°F, which is a touch warmer than normal for this time of year, so you won’t need a thick wetsuit, but you’ll still want a spring suit.
The Best of the Bunch: If you’re desperate, your best bet is Saturday, September 5th. The swell is a tiny 3 ft from the ESE, but the wind is glassy in the morning. It’s the cleanest, most peaceful window we get. For a more sizeable option, Monday, September 7th morning has 3 ft from the east with a 9-second period and clean cross-off wind. It’s the only day in the second week that offers any real hope. Both are small, so don’t expect barrels, but it’s the best we’ve got.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Kennebunk Beach is 17 km (11 miles) from Biddeford. If you plan a vacation in Maine, look for hotels and other accommodation in Biddeford. Biddeford has rooms for a wide range of budgets as well as car hire and transport links.
